The present invention relates to a chill program cross-debugging method of simultaneously cross-debugging several chill programs in a host system using a connection manager of a target system in software development of a real-time embedded system such as an exchange system.

Cross-debugging of a chill program refers to debugging a chill program on a target system (such as an exchange system) that does not support interactive debugging sessions in real-time embedded system development such as an exchange.

The conventional cross-debugging method runs a remote server on the target system to support the minimum functions by debugging such as program execution control function, memory and register value reference and change function, and most debugging functions are host chill debuggers. Debugged while communicating with the remote server of the target system using the communication line.

This conventional debugging method first runs the remote server on the shepherd system. Then, the host chill debugger runs on the host system, and then establishes a communication path between the host chill debugger and the remote server. After the above steps, a debugging session is established to perform cross debugging of one program. When a debugging session is created, the host chill debugger downloads the executable file to be debugged on the target system and debugs the executable file using debugging commands. After debugging this executable, the host chill debugger and the remote server break the communication path and finish their execution.

However, this conventional debugging method is cumbersome for debugging, because whenever a user wants to debug a new remote server, the user who wants to debug the new remote server must run on the target system and run a host chill debugger. There was a problem that was painful and time consuming.

In order to solve the above problems, the present invention introduces a connection manager to a target system, and when a cross-debugging request of a new executable file is received from the host chill debugger, the connection manager automatically creates a new remote server so that a new debugging session is created. The goal is to provide a way to cross-debug a chill program.

In order to achieve the above object, the present invention provides a cross-debugging method applied to a system having a host system including a host chiller and an object system for executing a remote server, wherein the connection manager is executed in the target system. A first step of executing a new host chill debugger in the host system; A second step in which the host manager debugger requests the connection manager to establish a logical communication path, and when the logical communication path is established between the host chiller and the connection manager, the connection manager creates a new remote server; And a third step of releasing the logical communication path after the remote server performs cross debugging with the host chiller using a logical communication path, and terminating the remote server and the chiller debugger. Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention; 1 is a block diagram of the entire system to which the present invention is applied, 101 is a host chiller debugger, 102 is a general operating system, 103 is a computer, 104 is a connection manager, 105 is a remote server, 106 is an operating system for a switch, and 107 is Each exchanger is shown.

As shown here, chill cross debugging consists of a host system running a host chill debugger 101 and a target system running a remote server 105. The two systems are then connected to a physical channel, such as a serial line or an Ethernet connection, for transmission of commands and results.

The host system refers to a general general purpose computer system, and the general purpose operating system 102 is executed on the computer 103, and various applications are executed in the environment.

Host chill debugger 101 is a CHILL program debugger for host systems that supports interactive debugging sessions on the host system. Therefore, the host chill has been added to the host CHILL for cross debugging to communicate with the target system.

General purpose operating system 102 provides a system call such as that provided by host chill debugger 101 to provide socket programming of a Unix system to establish a logical communication path with a target system. The computer 103 is then physically connected with the exchanger hardware of the target system.

On the other hand, the remote server 105 executes an executable file for the target system, and commands such as single-stepping, memory and register value reference and change required for debugging from the host chill debugger 101. Accepts, performs this and returns the result.

The connection manager 104 establishes a logical communication path with the host chill debugger 101 and performs a function of creating a remote server 105. This communication path is then made available to the remote server 105 to allow communication between the host chill debugger and the remote server 105.

The exchange operating system 106 is a control system level operating system of the exchange system, and provides an effective function for executing and managing a large variety of complex and various types of application software. Its main functions include process management, message transfer management, time management, memory management, input / output management, file management, and so on, so that the connection manager 104 can establish a logical communication path with a host system. It provides the same system calls that are provided by programming.

The exchange 107 is physically connected directly with the computer hardware of the host system, which is called a physical communication path.

2 is a conceptual diagram of cross debugging of a plurality of chill programs according to the present invention, and shows an execution model when several users log in to a host system and cross debug the n programs.

In conventional cross debugging, there is no connection manager. Therefore, to debug multiple applications on the target system, each time you debug, you must manually run a new remote server on the target system. However, with the introduction of the access manager, the access manager can automatically create a new remote server on the target system.

3 is a flow chart according to the present invention. First, a connection manager is executed on the target system (301), and a new host chill debugger is executed on the host system (302) to cross debug the new executable file. Thereafter, the host Chill debugger created in the host system requests the connection manager created in the target system to establish a logical channel (303), and when logical communication is established between the host Chill debugger and the access manager, the connection manager establishes a new remote server. Generate 305. The connection manager then runs a new host fill debugger on the host system to perform new cross debugging.

Meanwhile, the remote server generated by the access manager performs cross debugging with the host Chill debugger using the communication channel (306), after completing the cross debugging (307), and releases the logical communication channel (308). The remote server and the host Chill debugger are terminated (309). On the other hand, if a cross-debugging request from a new host Chill debugger is received during each process, the connection manager stores it in a waiting queue for processing after completing the debugging.

As described above, the present invention is simple and convenient by introducing a connection manager to the target system and allowing the connection manager to automatically create a new remote server by creating a new remote server when a cross debugging request of a new executable file is received from the host chiller. This has the effect of enabling multiple cross debuggings at the same time.
